The main purpose of this thesis is to research and develop three different kinds of battery chargers of resonant-switch converters. Starting with the zero voltage switch and the zero current switch converters, which employ the quasi-resonant converter technique, we gain the best parameters of the resonance components from the characteristic curve diagrams of these two converters. Then we design battery chargers based on these two structures and use them to experiment on lead-acid batteries.

中文摘要本论文之主要目的在於研制三种不同的共振开关式转换器蓄电池充电器，先探讨半共振式技术的零电压以及零电流转换器，利用这两种转换器的特性曲线图设计出共振元件最佳的参数值，以这两种架构作为蓄电池充电器，来对铅酸蓄电池做充电测试，经实验测得，零电压切换半共振式降压型转换器之充电器的开关在零电压的时候导通和截止。
